Astoria's interference help in this matter is definitely appreciated! Vex herself would be happy to negotiate terms for the new merfolk if they need it, and may shake a few hands to agree on exchanging jewelry and fruit. A deal's a deal, and she might as well use that power of hers for the refugee's benefit.

And that would have been my next question. XD Vex didn't get to hang out much with Nessie when exploring the cave network, but she would at least reassure the newly arrived merfolk that they're safe to approach.
